Last year, church groups helped make Mel Gibson's "The Passion of the Christ" a box-office hit after traditional distributors shunned it. This year, they are serving as the actual box office for "Left Behind: World at War," The Washington Post reports. The movie is the latest in the "Left Behind" series about the end times, and the impending rapture when some Christians will be sucked into heaven while unbelievers face hell on earth. The "Left Behind" series has been panned by secular critics like James Berardinelli as "Cheesy. Silly. Moronic. Dull. Plodding. Torturous."
